USD import custom data

Hallo,

I’m searching for a possibility to load custom data to Unreal Engine 5 using the USD file format (currently I’m using version Unreal Engine 5.03.). Let’s, for instance, assume the data is attached to an USD Xform node in the imported file, e.g.

    def Xform "MyXformNode"
    {
        custom string myID = "..."
        ...
    }

This seems to be a valid USD file which can be created/loaded using the standard Pixar USD library (GitHub - PixarAnimationStudios/USD: Universal Scene Description).

However, it seems to me that no data is imported to the Unreal using the “USDImporter” Plugin.

Is it possible to load such kind of data somehow?

Or is there a way to e.g. extend the USD schema definitions in Unreal accordingly to process custom data at Unreal import?

Bye, Julian
